BUPEBHEATING-MANIFOLD.

Specification of Letters Patent.

Patented Oct. '7, 1919.

Application led January 5. 1918. Serial No. 210,510.

Y '0 all 'whom t may concern:

lie it known that l, JOHN (i. LAWSHE, a citizen of the United States, and a resident of Flemington, in, the munty of Hunterdon and State of New Jersey, have invented a new and Improved Superheating-Manifold, of which the following is a full, clear, and exact description.

The invention relates to internal combua tion engines suoli as are used in automobiles and similar vehicles, and its objecl'l is to providi@l a new and improved superheatin manifold arranged to supplement the usua explosive mixture with a superheated charge of air or steam. or both to enrich the explosive mixture and thus render. the same more forceful.

In order to accomplish the desired result, the manifold is provided with the usual passage adapted to connect the caibureter with the en ine cylinders, and is also provided with tie usual exhaust chamber connected with the exhausts of the engine Cylinders, and a mixing and superheatin chamber which is integral with themaiiifgld and extends within the said exhaust chamber, the said mixing chamber being connected with the said passage and being highly heated by the exhaust gases passing into the said ex` liaust chamber, the said mixing and superheatiiig chamber being provided with means for supplying it with air or steam or a mixture of both.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indi cate corresponding parte in both views.

Fi ure 1 is a sectional side elevation of the super eating manifold as applied to a Ford automobile engine, parts being shown in elevation; and

Fig. 2 is a transverse section of thersame on the line ,Of- 2 of Fig. 1.

The manifold 10. is provided with the usual passage 11 connectcdat one end with a carbureter 12 and provided at its other end with two branches 13 and 14 connected at their ends at 15 'and 16,with the valves' of the engine cylinders 17 to which the manifold is fastened by bolts 18 or other suitable fastenin means. Within the manifold 10 is form an exhaust chamber 2O connected at 21, 22, Q3 and 24 with the exhaust valves of the engine cylinders, and the exand superheatin l telit haust chamber 20 is provided with an outlet 25 connected with a mufllcr or the like.

Within the exhaust chamber 20 is arranged a mixing and sulperheating chamber 30 forming an integra part of the manifold and located adiacent the junction of the branch pipes 1.3 and 14, as plainly indicated in F ig. 1. This mixing) and superheating chamber 3Q is connected y a port 3l with the branch pipes 13 and 14, and the said mixing elia-m ber is provided opposite the said port 31 with an inlet 32 forming an integral part of the manifold and extending through the exhaust chamber 20. Into the outer end of the inlet 32 screws a nipple 33 of a valve 34 having a valve body 35 in which is inlounted to turn a valve plug 36 provided with avalve stem 37 journaled in the ends of the valve body 35. The outer end of the valve stem 37 is irovided with a handle 38 under the controi of the operator for turning the valve plug 36 in the valve casing 35. The valve plug '36 is provided with tWo ports 40 and 41 of which the port 40. is adapted to register with a'port 42 formed in the valve casing 35 and leading to an air inlet 43.formed integrallyon the valve body 35.. The other valve port 41 is adapted to register with a nipple 44 connected with a suitable steam supply,Y for instance, the radiatorof an automobile, to allow the steam to pass .into the valve 34 to mix with the air passing into the valve through the air inlet 43. The mixture of air and steam passes by wayfof the nipple 33 and the 'inlet 32 into the mixing and superheating cham ber 30 in which the air and steam are intimately mixed and are heated by the exhaust gases within the exhaust chamber 20 prior to thr passa e through the port 31 in 4t e brano' pipes 1` and 14. In order to i oil tate the commingling of the air and steam and to insure thorough superheating thereof, the mixing and lsu erheatin chamber 30 is preferably provide with ba es 50 and 5l to provide a long passage for the mixture of air ands in throu li the chamber 30.

It will be notce that by theoperator manipulating th valve plug 36 more or less air and steam can be admitted to the mixing chamber '30, and the air or the steam may entirely cut oli' on the operator correspondingly t -in' g the valve 36 so that only supehea d air or sucated steam passes to he explosive mixture traveling throughthe branch pipes 13 .and n.14 on their way from the carburetor to the engine cylinders.

It is understood that by the arran ement described the mixin and su er eating chamber 30 is highly ea-ted by t e 'exhaust gases passing into the exhaust chamber especially as the said mixing and superheating chamber forms an inte al. art lof the manifold and extends wit in t-e exhaust chamber 20.

It will further be noticed that the air or the steam or a mixture of both is highly ,heated prior to enterin the passa es for the explosive mixture an consequent y such mixture is enriched and thus rendered ex- .f .Deedingly powerfull' Having thusdescribedpiny invention, I
